AB  - Studies indicate that the soil, water and consequently foodstuffs in Serbia are significantly poor in zinc (Zn), and thus, it is likely that there is a Zn deficiency in the Serbian population. This study examined the Zn status in multiple clinical samples, including body fluids (serum, cerebrospinal fluid), whole blood and Zn-rich solid tissues (thyroid and brain tissue). Differences between sex and age were also considered, and comparative analysis of Zn status with other world populations was performed. Serum samples from a large number of Serbian adults approximately had twofold lower Zn amounts when compared to other populations. A similar trend was obtained for whole blood. Males had significantly higher amounts of Zn in serum, whole blood and thyroid tissue samples than females. Higher amounts of Zn were observed in the group older than 50 years. Importantly, in thyroid and brain tissues, Zn was 10- and 20-fold lower, respectively, than reported in the literature. Our results indicate that the population in Serbia could be considered Zn deficient. Therefore, adequate oral Zn supplementation and/or foodstuff fortification should be considered to prevent the deleterious effects caused by Zn deficiency.

AB  - Introduction: Any substance that induces production of free radicals can be a potential cause of brain damage. The aim of our study was to investigate the relationship between some metal ions and oxidative stress biomarkers in the blood of patients with brain tumor and hydrocephalus. Material and methods: Our study included 27 control subjects, 24 patients with brain tumor and 21 patients with hydrocephalus. The activities of superoxide dismutase (CuZn SOD), catalase (CAT), glutathione peroxidase (GSH-Px), glutathione reductase (GR), glutathione S-transferase (GST) and acetyl cholinesterase (AChE), as well as concentrations of reduced glutathione (GSH), lipid peroxides (TBARS) and sulfhydryl groups (SH) were analyzed in the plasma and red blood cells (RBCs) of patients. We also determined the concentrations of Mn, Ni, Co, Cu, Zn, As, Se, Cd, Hg and Fe. Results: The higher activity of SOD and concentration of GSH in both investigated groups could indicate higher oxidative stress. We also observed decreased levels of SH groups in both groups of patients. In both groups of patients we detected decreased concentrations of Ni, Co, Zn and Fe (and Mn in brain tumor patients) and increased concentrations of As, Se and Cd in the blood. Interestingly, we observed a higher concentration of Cd in both plasma and RBCs of hydrocephalus patients compared to the patients with brain tumor. Conclusions: There are strong correlations between some metal ion concentrations and certain oxidative stress biomarkers in the blood of patients, which supports our hypothesis, but the observed trend needs to be further investigated.

AB  - The pathogenesis of malignant brain tumors (MBTs) should be better understood due to the evident association between prolonged exposure to metals and increased risk of MBTs. The present research aimed to find trace metals that could contribute to the pathogenesis of MBTs. Essential trace elements (Mn, Co, Zn, Cu, Se) and relevant toxic metals (Al, Ni, As, Sr, Cd, Ce, Pt, Pb, U) in the serum, cell fraction (CF), cerebrospinal fluid (CSF) and cancerous tissue (CT) samples of MBT patients were analyzed. The results were compared with sex- and age-matched control groups. For the first time, this research showed that elemental profiles of serum, CF, CSF and CT samples in MBT patients were significantly altered compared to the appropriate controls, as well as that higher contents of trace elements (particularly Mn, Se, and Pb) could be involved in the pathogenesis of MBTs. However, the most noticeable change found was the elevated U content, indicating its considerable role as a major cerebral discriminator of the presence/absence of MBTs. The U/Se ratio could be considered as an appropriate blood marker in diagnostic MBT evaluation. The reported results could contribute to better understanding of the poorly understood pathogenesis of MBTs. Furthermore, the reported results could highlight a molecular basis for the pathophysiological changes caused by the hazardous effects of trace metals on brain homeostasis.
